I took it to 140ft a month ago. It complained and turned the screen yellow as a warning, but readings in the built in Depth app (which measures depth, water temp, and dive time but is NOT a dive computer) matched my dive computer exactly at that depth and all other depths.

It’s rated as water resistant to 100m, 300+ feet - it’s just the software and measurement sensor bits that get queasy at 130ft.

The software APIs for measuring depth have an enum for this: https://developer.apple.com/documentation/coremotion/cmwater...

Was curious about this myself. I've gone deeper than 40m on a recreational dive, blue hole I think. Obviously they aren't 'supposed' to do that, but it obviously routinely happens and it'd be a bummer if your fancy watch dies at that depth
